METALLIC TIE.

To all whom it may concern.

Be it known that I, ALVA G. DINKEY, a resident of Pittsburg, Alleghenycounty, Pennsylvania, have invented a new and useful Improvement inMetallic Ties, of which the followin is a full, clear, and exactdescription, re erence being had to the accompanying drawings, formingpart of this specification, in which Figure 1 is a perspective viewshowing a railway cross-tie having the rails of a railway track securedthereto, and constructed in accordance with my invention; and Fig. 2 isa sectional end elevation on a larger scale of the tie shown in Fig. 1.

My invention relates to metallic crossties used in the construction ofthe tracks of a railway and the object of the invention is to provide astrong and durable metal tie in which a broad substantial base orbearing surface is presented to the road bed and in which the metal isdistributed so as to afford the maximum strength with the minimum amountof material. To that end, the invention consists in constructing ahollow metal tie having a flat top or rail bearing surface connected bysubstantially vertical walls with oppositely projecting flanges with theflanges extending on opposite sides of each of the side walls andforming the base of the tie.

In the drawings, 2. represents a rolled metal cross-tie having trackrails 3, secured thereto. In the rail fastening shown, metal clips 4 areemployed which are bolted in place to secure the rails to the tie, theclips being held in place by means of the securing bolts 5, suitablebolt holes being provided in the tie for this purpose. The manner ofsecuring the rails may be varied, however, and any approved securingmeans may be employed for use with my improved tie.

The rail bearing surface 6 is preferably formed integral with verticallyextending side walls 7 and the lower edges of the side walls areprovided with oppositely projecting flanges 8, 8 The side walls 7,together with the top surface 6 and the inwardly projecting flanges 8*,form a hollow rectangular inclosure, while the flanges 8 projectoutwardlybeyond the side walls 7 so as to increase the width of the tieand in this way provide a wider bearing surface for the tie on the roadbed of the railway track.

In the construction of the tie, I first form Specification of LettersPatent.

Serial No. 454,880.

a rolled metal shape which is substantially the same in cross-section asthe commercial I-beam, in which the web portion connects oppositelyprojecting flanges which are located on the opposite edges of the web.The blank is then subjected to a bending operation in which the web isbent so as to form three sides of the rectangular inclosure, the flangeportions 8 together with the three sides formed by the web portion,forming the four sides of the rectangle. The flange portions 8 projectoutwardly beyond the width of the tie defined by the substantiallyvertical sides 7 and in this way increase the width of the base of thetie.

In some cases, it may be found desirable to make the thickness of thetop side 6 greater or less than that of the side wall 7, this change inthickness being effected during the rolling operation.

The advantages of my invention will be apparent to those skilled in theart. The tie can be easily and cheaply formed and when formed in themanner shown, a metallic cross-tie is provided having great strengthwith a minimum amount of material. The oppositely projecting flangeportions pro vide a wide base and afford a large bearing surface on theballast or road bed. The longitudinal opening through the tie permits ofthe rail-securing means being easily and quickly applied.

The ties are durable and may be formed in multiple lengths and afterwardcut to the desired size. The opening through the tie may be filled withplastic or other material when desired or may be partly filled.

Modifications in the construction of the tie may be made within thescope of my invention. The vertical height of the tie relative to thewidth may be chan ed, the width of part of the flanges relatively to theother flanges may be varied and other changes may be made.

I claim A substantially U-shaped cross-tie of rolled metal,having rolledflanges projecting in opposite directions from each leg of the tie atsubstantially right angles thereto and in the same plane with oneanother, the top of the tie being flat to support rails, the innerflanges coming into close mutual proximity, which flanges, together withthe top and legs, form a hollow substantially rectangular tie closedthroughout its length arcuate bend, and a fillet between each leg andthe top of the tie at the interior of the tie, substantially asdescribed. 10 In testimony whereof, I have hereunto set my hand.
